Is aldehyde or alcohol more soluble in water?
The oxygen atom of the carbonyl group engages in hydrogen bonding with a water molecule. The solubility of aldehydes is therefore about the same as that of alcohols and ethers.
Why are alcohol more soluble in water than aldehydes?
In alcohols, aldehydes and ketones, an electronegative Oxygen atom is present which makes them polar in nature as it attracts the shared electron pair towards itself and acquires a slight negative charge, leading to development of polarity in the molecule, in alcohols oxygen of water can form Hydrogen bond with …
Is alcohol more soluble in water than ketone?
Carboxylic acids are more soluble in water than alcohols, ethers, aldehydes, and ketones of comparable molecular weight. – They form hydrogen bonds with water molecules through both their C=O. Physical Properties – Water solubility decreases as the relative size of the hydrophobic portion of the molecule increases.
What is more soluble water or alcohol?
In ethyl alcohol, the hydrogen atom is bonded to an electronegative oxygen atom. Thus, hydrogen bonding is possible in ethyl alcohol. The hydrogen bonding in ethyl alcohol is shown in the following image. … Thus, ethyl alcohol is more soluble in water than dimethyl ether because alcohol contains hydrogen bonding.
What makes an alcohol more soluble in water?
Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water.
Which is highly soluble in water?
Owing to the high hydration energy of Be2+ (-2494kJmol-1) in forming [Be(H2O)4]2+ beryllium fluoride is very soluble in water. All the other fluorides, MF2 which are ionic are almost insoluble in water as their as their hydration enthalpies are not able to outweigh their lattice enthalpies.

Is aldehyde more polar than alcohol?
(4) KETONE and (5) ALDEHYDE: A comparison of the boiling points of aldehyde and ketone with the corresponding alcohol shows that the alcohol is more polar due to its ability to hydrogen bond. Since ketones and aldehydes lack hydroxyl groups, they are incapable of intermolecular hydrogen bonds.
Which of the following ketones is the most soluble in water?
The most important ketone is acetone (CH3COCH3), a liquid with a sweetish odour. Acetone is one of the few organic compounds that is infinitely soluble in water (i.e., soluble in all proportions); it also dissolves many organic compounds.
